Path

Not to be confused with PATH.

Path is a two-dimensional esoteric programming language invented by User:masalt in Python 3.

Instructions

Path has the following instructions:

Instruction	Definition
└	Faces pointer north or east, depending on the direction beforehand (unless it's facing either already).
┘	Faces pointer north or west, depending on the direction beforehand (unless it's facing either already).
┐	Faces pointer south or west, depending on the direction beforehand (unless it's facing either already).
┌	Faces pointer south or east, depending on the direction beforehand (unless it's facing either already).
┴	Faces the pointer north (if it's not already).
┬	Faces the pointer south (if it's not already).
├	Faces the pointer east (if it's not already).
┤	Faces the pointer west (if it's not already).
?	Faces the pointer in a random direction.
│	Continues moving the pointer vertically.
─	Continues moving the pointer horizontally.
┼	Continues moving the pointer vertically or horizontally.
█	Reverses the pointer's direction.
+	Increases top of the stack.
-	Decreases top of the stack.
&	Pushes 0 to the stack.
$	Pops top of the stack.
~	Takes user input (string) and pushes the character ASCII value to the stack.
#	Takes user input (integer) and pushes the value to the stack.
:	Duplicates the top stack value.
.	Caches the top stack value and pops it.
,	Caches the ASCII character of the top stack value and pops it.
%	Swaps the top two stack values.
^	Faces the pointer north of the top stack value is greater than the second.
v	Faces the pointer south of the top stack value is greater than the second.
>	Faces the pointer east of the top stack value is greater than the second.
<	Faces the pointer west of the top stack value is greater than the second.
J	Joins the top two stack values (B;A)
j	Joins the top two stack values (A;B)
p	Prints cache.
g	Pops the top stack value and adds that item of the stack (from the back).
r	Takes the top two stack values (A,B) and replaces item of A stack with B.
w	Takes the top stack value (A) and waits for A seconds.
q	Takes the top stack value (A) and caches line A of the code.
0-9	Pushes number at the pointer to the stack.
×	Pops the top two stack values and pushes their product to the stack.
÷	Pops the top two stack values and pushes the rounded quotient to the stack. (A / B)
±	If the proceeding instruction is +, pushes the sum of the top two values; If the proceeding instruction is -, pushes the difference of the top two values (B-A). Skips next instruction (+,-).
=	If the top two values are equivalent, pushes 1, otherwise pushes 0.
@	Ends the program and prints all cache.
